The dc Dielectric Test Sets measure leakage current while applying a dc voltage at or above the insulation system's operating level. This measurement aids in determining the insulation system's ability to withstand overvoltages such as lightning strikes and switching surges.

The 5- and 15-kV Megohmmeters are high-voltage, line-operated instruments. They provide a continuously variable test voltage for highly sensitive insulation-resistance measurements of all types of electrical equipment and power cable.
The instruments are designed to withstand harsh field conditions, and feature tough, impact-resistance casing, removable lids and adjustable carrying straps. For complete portability, there is ample room in each case to store cables and the instruction manual.

Earth
Testing covers the testing of earth electrodes and the measurement of soil
resistivity. The Megger line of advanced clamp-on ground resistance testers
set new standards in terms of access, performance, features, simplicity
of operation and safety. These units are designed with flat core ends to
prevent dirt build-up, ensuring measurement integrity and improved reliability
over products with interlocking teeth.

HiPot
Testers available from Megger are used to test the dielectric strength of
electrical insulation and ground circuit continuity of three-wire appliances
and other devices, either in the field or at the end of a production line.
All instruments meet the UL 120 k-ohm requirement.

For
use on any grounded electrical system, DETEX Voltage Detectors are available
that cover a range from distribution class to transmission line voltages
up to 550 kV. Biddle offers six electronic "beeper" models and one model with LED indication for greater visibility when testing indoors.

The Megger range of clampmeters are an invaluable tool; since there is no need to switch off or break the circuit. They offer a safe, non-intrusive way of diagnosing faults on live electrical circuits.
All the equipment has been developed and manufactured for easy of use, application versatility, flexibility and with the goal of producing accurate instruments.

Whether locating cable faults or testing the integrity of communication, power, or control cables, TDRs from Megger provide fast and accurate results. Each unit is a safe, low-voltage tester that can be used on virtually all cable types, whatever their power rating.

Transformers are very reliable devices and can provide service for a long time if maintained and serviced regularly. They are also the single most costly item in any substation. To protect against failures that can result in costly repairs and long periods of downtime, trust your transformer to the accurate and reliable test equipment from Megger. The best insurance against transformer failure is to ensure that they are properly installed and maintained. The complete line of Megger equipment makes testing easy and accurate.

From Megger, these highly accurate, easy to operate instruments measure resistance with resolution as fine as 0.1 micro-ohm. Digital micro-ohmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds just to name a few of the applications. Megger has models available for testing using test currents from 0.5 mA to 100 amps covering a multitude of applications that require precise low-resistance measurements.

The Motor and Phase Rotation Tester permits the electrical contractor or industrial maintenance electrician to permanently connect and tape the terminals of the motor being installed, without having to first energize the motor by a temporary hookup from a power source, if available, to determine motor rotation. Therefore, the test set eliminates the need for temporary connections that can be time consuming, costly and quite hazardous, particularly where many large, high-voltage motors are involved.

Research indicates that internal battery cell impedance increases with the age and discharge history of a cell. Since interruption in electrical service can spell disaster, a reliable backup power system is critical so that when conventional power fails, costly service outages can be avoided.
The BITE™ family of products provides meaningful data on battery health without significant expense or reduction in remaining battery capacity. The BITE products are designed for on-line ac impedance and dc terminal voltage measurement of secondary batteries.

Megger offers a wide assortment of rugged, high quality hand-held instruments which are used to test electrical wiring and other components in residential buildings, manufacturing facilities, government entities and other general business operations.
